This vehicle has experienced multiple substantial defects, several of which directly endangered my family, including an infant, and rendered the vehicle unsafe and inoperable for extended periods despite warranty repairs. Summary of defects and failures: 1.Electronic door locking failure The vehicle experienced an electronic malfunction that caused the doors to randomly lock, resulting in my infant being locked inside the vehicle when we exited. This wiring defect was later repaired under warranty but represents a serious safety failure. 2.Fuel pump recall and highway breakdown While driving my family of six on a major highway over an hour from home, the recalled fuel pump failed while in motion, leaving us stranded on the side of the highway. We were forced to arrange an Uber for transportation. This incident placed my family in a dangerous situation and constitutes a major safety-related defect. 3.Transmission failure and extended inoperability The vehicle suffered a transmission failure that rendered it unsafe and inoperable. The dealership required over one week to schedule service and more than two additional weeks before the vehicle was inspected and repaired. The vehicle was out of safe driving condition for approximately one month. Upon return, the vehicle experienced additional failures, including a dead battery. 4.Known poor design defect – rear entertainment screens The rear entertainment system screens cracked due to a widely known poor design and placement issue, unrelated to misuse. 5.Rear headrest internal mechanism failure The internal mechanism of a rear headrest failed and requires replacement, further demonstrating ongoing quality and safety concerns. Due to the number, severity, and safety-related nature of these defects—combined with cumulative downtime exceeding 30 days—I have lost all confidence in this vehicle. I no longer consider it safe or reliable for transporting my family.

vehicle infotainment system will randomly "restart" or shut off completely when vehicle is being drove, but will still be playing music also all time and temperature (outside temp) will freeze when this happens. it also make the battery drain when this happens. the only way to get the screen to come back on weve tried is to disconnect battery. weve replaced the battery, weve had a chevy dealership look into it. no one can figure out what is happening. Now it is happening more and more. we also do not receive updates anymore to the infotainment system. the dealership had to manually do it a year ago. also will not keep our proifile signed in at all. always says were stuck in guest mode. says we have full storage when there is not any apps downloaded.

First fuel system failure occurred at ~3500 miles. Pulled out of driveway, shifted into drive and vehicle stalled and would not restart. Fuel pump replaced first then fuel module replaced resolving issue. Now at 12,100, vehicle again shut down at a major intersection and would not start. Vehicle has been towed to dealership. The vehicle failure mechanism locks the car in park and leaves all electronics powered on. Fortunately I was able to get the front wheels strait during one sputtering start attempt so it could be DRAGGED straight onto the tow truck. Able to power off radio and ac buT no other electronics would shutdown, dash display, resulting in total battery drain. Can only lock drivers door with key so vehicle is outside dealer service center on a weekend unlocked. This the second failure of the same component. This abrupt failure creates a completely unsafe situation leaving you stranded unable to move. This vehicle is an expensive failure and based on a second recurrence, the related electronic component issue has not been resolved. First occurrence Chevrolet provided a free year of OnStar due to me not feeling safe with this vehicle. Now just after this expired, the same failure has occurred. Buy this vehicle back from me Chevrolet at my purchase price. First occurrence took 3 hrs for a tow truck to pick up the car which was fortunately in middle of my street. This current failure was 2.5 hrs stuck at a stop sign in the middle of a major intersection. Thank God I was not on the interstate.

The vehicle was manufactured with a push button transmission gear selector. If there is an electrical issue(ie. dead battery, electrical short, engine failure, etc) you cannot shift transmission gears. If I pull into my garage, notice a burning smell coming from engine area, possibly an electrical short, I cannot put vehicle in neutral to push out of garage in case it does erupt into a fire and not burn down my house. Recently my dead battery caused the tow company to lift the back end and pull it our of garage. General Motors did not install an override to put transmission in neutral in an emergency. The transmission will only shift if the engine is running. Imagine driving on a road or stopped at a traffic light and the engine stalls, will not restart, good Samaritans offer to push you off the road, but can't shift to neutral. Dealerships have a hydraulic lift they place under rear tires to move vehicle around service area. As a retired law enforcement officer, many times we had to move vehicles out of the way until wrecker serviced arrived. I feel this is definitely something that has to be addressed and corrected before major damage occurs or lives are endangered.
